TOOL-HANDLE.

Application filed October 21, 1915.

To all to 7mm it may concern Be it known that I, GEORGE W. IIAnRIs, acitizen of the United States, residing at Hobart, in the county of Kiowaand State of Oklahoma, have invented certain new and useful Improvementsin Tool-Handles, of which the following is a specification.

This invention relates to tool handles and more particularly to a handlewhich is especially adapted for use in connection with planes althoughthe novel features of construction embodied in the present invention,

may be employed in a handle designed especially for use in connectionwith various other kinds of tools as, for example, saws and the like.

It is the aim of the invention to so construct the handle that it willreadily conform to the shape of the hand when closed about the handle,thereby rendering the tool to which the handle is appplied, more convenient and less fatiguing to handle.

Another aim of the invention is to so form the grip portion of thehandle that it will constitute an effective abutment for the heel of thepalm of the hand so that considerable force may be exerted against thehandle in the use of the tool without tiring the hand to the same extentas where the ordinary form of handle is employed.

In the accompanying drawings: Figure 1 is a perspective view of a planeprovided with a handle formed in accordance with the present invention.Fig. 2 is a side elevation of the handle. Fig. 3 is a rear elevationthereof. Fig. 4 is a horizontal sectional view on the line i-d of Fig.2. Fig. 5 is a diagonal section on the line 5-5 of Fig. 2. Fig. 6 is aview similar to Fig. 5, taken on the line 66 of Fig. 2.

In the drawings the numeral 1 indicates in general a tool such, forexample, as a plane and as aside from the handle the tool is of theordinary construction, further description thereof is deemedunnecessary.

The handle embodying the present invention includes an attaching baseand a grip portion, the base portion being indicated in general by thenumeral 2 and having a forward extension 3 provided with an opening 4through which may be fitted a securing screw or the like indicated bythe numeral 5, which screw enters the body of the plane 1 andconstitutes a means for securing the handle to the said body. Arelatively long bolt is to be fitted through a bore Specification ofLetters Patent.

7 extending longitudinally through the handle and this bolt constitutesa means for securing the handle in place.

Generally speaking, the grip portion of the handle, indicated by thenumeral 8, is curved upwardly and forwardly from the attaching base 2 ofthe handle and its upper surface is convex from its forward to its rearend, the grip at its upper end and at its rear side being provided witha rearwardly extending nose 9, the upper face of which constitutes acontinuation of the upper face of the grip proper. The under surface ofthe nose 9 is transversely and longitudinally convex so as to fit snuglywithin the hollow of the hand between the base of the thumb andforefinger. At a point immediately below the nose 9 the grip of thehandle is elliptical in cross section as clearly shown in Fig. 6 of thedrawings, this portion being in dicated specifically by the numeral 10.Below the portion 10 the handle is provided at its under side and at itsrear with a wing 11 which projects laterally and rearwardly from thebody portion of the grip and the lateral or forward side of which,indicated by the numeral 12, constitues a continuation of the lateralface of the lower portion of the said body of the grip, the mergingsurfaces being concave so as to form a concave seat for the tips of themiddle, third and little fingers of the right hand when the handle isgrasped. The outer or lateral edge of the wing 11 extends along a curvedline gradually receding from the plane of the body port-ion of the gripand extends from the portion 6 to the attaching base 2, this edge at itslower end terminating at the rear side or edge of the said base and atthe plane of the bottom of the said base. The wing 11 constitutes anabutment for the heel of the palm of the hand, as before stated, and inorder that the heel of, the palm may comfortably seat against the saidwing, that face of the wing opposite the face 12 is of anti-elasticform, this face being indicated by the numeral 13. As will be apparentby reference to Figs. 4 and 5 of the drawings, the face 13 istransversely convex and terminates at one side at the outer edge of thewing and at its other side merges with the surface bf the body of thegrip at the righthand side thereof. The face 13 is concave from itsupper to its lower end, the body of the grip portion being, however,convex as indicated at 14, between the upper end of the outer edge ofthe wing and the upper end of the concave surface 13.

, From the foregoing description of the invention it will be apparentthat the grip of the handle is of such contour that it will snuglyconform to the hand when grasped and that due to the provision of thewing 11 and the peculiar formation of its forward and rear faces, thewing constitutes an ef fective abutment for the heel of the palm of thehand, thereby permitting of the application of considerable forceagainst the handle without, however, tiring the user of the tool to thesame extent as when a handle of the ordinary form is employed.

Having thus described the invention, what is claimed as new is:

1. A tool handle having a grip portion provided with a lateral wingconstituting an abutment for the heel of the palm of the hand, theforward face of the wing being transversely concave to form a seat forthe tips of the fingers when the handle is grasped.

2. A tool handle having a grip portion provided with a lateral wingconstituting an abutment for the heel of the palm of the hand, theforward face of the wing being transversely concave and merging with theadjacent lateral face of the body of the grip portion, and the rear faceof the wing being transversely convex and merging with the other lateralface of the said grip portion, the said rear face of the wing beinglongitudinally concave.

A tool handle comprising a grip portion curved in a general upward andfor ward direction and having its forward side longitudinally concaveand transversely convex, the rear face of the said body near the lowerend thereof being substantially obliquely disposed, the said gripportion being formed at one side and at the rear with a late allyprojectingwing longitudinally concave and transversely convex at itsrear side and having its said rear side merging withthe rear side of thesaid grip portion, the forward side of the said wing being transverselyconcave and merging with the adjacent lateral face of the said gripportion, the upper portion of the wing being gradually decreased inwidth until it merges into the surface of the rear and said lateral faceof the grip portion.

In testimony whereof I affix mysignature in presence of two witnesses.
